ELEVATING-TRUCK,

I Spacification'of Letters Patent. P ientgd 1113.1, 29, 1921 Application filedJuly 2, 1 15. Serial No. 37,6;54.

T0 aZZ whomit mag concern: i c I Be it known that I, DANIEL E. HENNEssY,

' aflcitizen of the United States, residing at I-lolyoke, county of Hamp'den, and State of Massachusetts, have invented certain new and useful Improvements" in Elevating- Trucks, of which the following is a clear,

' full, and exact description.

This invention relate'sto an improvement in elevating trucks. ofthe type in which an upper platform is elevated with respect to the base in order to pick up, 'carry about, and deliverloadsfrom pla ceto place.

' j The object of the invention is-to improve the construction of such i'tru'cks so as to facllitatefthe elevatmg of the platform by means ofjthe steering handle' acting as a lever and to render said steeringhandle free forup-and-down and lateral movement when desired for steering and hauling the truck from one place to another. r

A. further object is to provide secure lock 7 'ing means for holding the platform in raised position under all conditionsof use and which may be readily'unlocked when desired, to permit the platform to lower. a

' Further objects and advantages of the in- V vention will be apparent from the following description and accompanying drawings which disclose the preferred embodiment of my invention.

In the drawings, Figure l is a side elevation of the truck;

Fig. 2 isa plan of the same; a

Fig. 3 is an enlarged detail of the connection between the handle and the platform when the platform is raised the dotted lines showing the parts in lifting engagement, and

the solid lines showing the position of the same. cart-s when disengaged;

Fig. tis a plan of the parts shown in solid lines of 3;

Fig. 5 is a similar view showing theplatform lowered. the solid lines showingthc parts disengagedandthe dotted lines the position of thcparts. preparatory to engagement; and

Fig. 6 is a. view similar to Fig. 5 showing the" partsat a later stage after the same have been engaged.

Figs. 7 and 8 are detailed views of a moclified form of en a in member with a art a b a L. in section to show more clearly the slotted portion thereof; 7

1 both up Fig. 9 is an enlarged detail of the inside face of the end of one engaging arm.

" Referring more particularly to the drawings, the truck is of the usual type comprisingthe lower baseframe 1 supported onrear wheels fl 'and'front steering wheel 3 which has the usual head'35 swiveled in the frame forbeing manipulated tofst-eer the truck 'Upon the upper portion of the swiveled head 35 is pivotally mounted at 22 the steering handle 21, so'that when free and disengaged as hereinafter described, it may be moved anddown and laterally in guiding andhaulingthe truck.

/ fllhe upperplatform indicated at 2, is connected to the lower frame 1, preferably by means of swinging links 5 at the rear, and

(Sat the front; so that said platform may have an up-and-down movement with respect to said base frame.

and at 11 to the base, and the links 6 are pivotally connected at 12 to the platform and at 13 to the, base. A checking device 7 is pivotally connected at 14: to the cross member 8 at the rear of said base frame.

and at 15'to the cross member 9 at the for ward part of'saidpla-tform to check the too rapid descent of said platform when it is released and'allowed'to lower. This checking device may be of any. usual. construction common with door checks. and it is not fldeemed necessary to describe it further in v The links 5 are pivotally connected at 10 to the platform connecting said handle to the platform are preferablyas followsz Upon the cross-shaft 19- at the forward part of the platform 2.

ispivotally mountedan engaglngr member.

preferably constructed-with two spaced side arms 1? and 17 The engagin memher 16 is provided with angular slots, one

slot on the inner face ofv each side arm'17 and 17? formed by recessing out said side arms. such as 19 for arm 17, and 19 for arm 17 all as shown more clearly in F1gs.

o and 6. The opposite ends of these slots are open softhat the ends of a cross-pin 20 of the pin and thus supports the arm 17 against the tendency of gravity to restore it to. its lowermost position, and a second surface which engages a lateral side of the pin 20 and forms the positive connection between the ,p'latform and the handle. 7 Similar surfaces are provided in the modilied construction hereinafter described. It will be understood, of course, that the invention 18 not restricted to the particular connections between the platform and the handle which are herein shown and described;

Upon a bracket fixed to the forward part of thebase frame '1, is pivotally' mounted at Qta foot-lever 22. The footlever may be weighted so as to normally stay in the positions shown in Figs. 1, 3 and 6, but I, preferably provide a spring 29 to normally hold it in this position; This footdeverf has two depending arms, one short arm 25 at the left and one longarm 27 at the right. The longer arm .27 is adapted to abut against a boss 28 formedon the engaging member 16 for lifting said memberto' place it in engaging positlon relative to the handle, and theshort arm 25 is adapted to abut against the front part of th'e platform 2 when the latter is elevated, as shown in Fig. 1, to throw said.

,platform rearwardly to bring said links 5 as follows.

the positlon shown n SQllCl lines in Fig. 5

and 6 to the rear of their Vertical position for lowering the platform. The platform 2 .is adapted to be elevated to bring the links 5 and 6 forward of their ver ical positions that said links 6 will rest against a stop 37 on the base frame and thus tend to hold the upper platform locked in its elevated position, as shown in Figs. 1 and Under some circumstances, such as when traveling up a steep incline. it is desirable to provide further means for locking the 'plattorm in its raised position. and for this purpose the left a m 17 of the engaging member has a laterally extending boss '18 which is adapted. when said engaging merit her is released, to drop into the position shown in Figs. 3 and 4, and stand in front of a similar laterally extending" boss 26 fixed to the foot-lever 23 and thus form interlocking means to prevent the platform from being accidentally lowered.

Operation: The operation of the truck is Assume that the parts are in with the upper platform down and the handle 21 freely movable back and forth or are described by the cross-pin 20.

"gaging member 16 into the position shown in dotted lines in Fig. that the lower end of the slots 19; 19, will be above the The handle 21 is'then manipulated to bring the cross-pin 20 to theposition shown in dotted lines in Fig.5 and the foot-lei 'er is released to allow the engaging member to drop, bringing the slotted arms 17, 1. into engagement with the cross-pin 20,1155 shown in F G. The handle 21 may then be swung; forwardly and downwardly to elevate the platform to the position shown in Fig. 14 If, then, it isdesired to draw the truck and have the handleQZl free for steering the same, it isonly necessary to swing the handle backwardly to the position shown in solid lines in Fig. 3, whereby the pin v "will pass out the up er open ends ofthe slots 19, 19 and release the engaging member 16 so that it will drop into the. position, shown insolid linesin 3. When the engaging member drops into this posi tion, it will be noted that boss 18 stands in front of the boss 26 on the foot-lever .u')- as shown in Fi 4:. and thus any backward movement of the platform necessary for descent is prevented. The truck may then be drawn by meansof the handle 21 which is freely movable in all directions. d hen it is desired to release the load, the footlever 23 is again operated to depress the boss 26 below theboss l8 and thus permit the platform to swing rearwardly when. by the furthermorement of the footdever 23, the arm 25 is brought to bear against the platform 2 for throwing it rearwardly.

The platform will then fall into the position shown in Fig. 5, its descent being controlled by the checking device 7. M

In Figs. 7, 8 and 9, l have shown a modified form of engaging member for being connected with the handle 21. This member comprises pivoted side arms 11: similar to emniging member 17 heretofore described and at the outer ends of ti ese arms are provided slots 119 in the inner face of said arms, which slots are open only at their upper ends as at 120 see Fig.

llO

These slots furthermore, ar formed with an offset portion 121 at their lower end so as to retain the pin 20 therein. In. Fig. 7

the parts are illustrated with the upper platform down, and as therein shown, the enmemberll? may be moved upward-lby the operation of the foot-lever 23 to bring the pin 20 within the upper end of l slot l20. ln dotted lines I have shown the handle and en a 'm member ust )lQVlOLlS b in 23 i to the entrance of the pin 20. in slot lQt) and in solid lines the position of the parts when the handle has been swung slightly forward the handle.

toreta-infthe' pin within the slot The platform may then be lifted by the operation of the handle as described in connection with the previous figures. In Fig. 8 is shown the positionvof the parts with the platform elevated,- and in solid lines the' permitting thereafter free movement of the handle 21 both up and down and laterally.

It will be noted from an examination of the drawings thatli'n both forms of connect ons-here n showniand described, the cone struction' and arran'geni ent oif the slot-is such; that the backward movement of the pm 20 not only'carrieslthe pin out ofthe slot, but a continuation Jot this movement, in the event that the link or engaging member 17 fails to fall under" the action of gravity, will insure the'movement of-the engaging member 17 out ofthe path ofmovem'ent of iVhile I have shown and described two embodiments *of my invent om it 1s obvlous that various changes in details may be made and equlvalent constructions adopted for the same urfose without-dc artin from a a the spirit of my invention as set forth in the following claims.
